The epididymal fat is required for the maintenance of normal spermatogenesis, and the lipectomy of epididymal fat at different postnatal age results in disrupted expression patterns of several testicular steroidogenic enzymes. The current research examined the effect of epididymal fat lipectomy at different postnatal ages on expression of cytochrome 5α-reductase I, cytochrome P450 aromatase, androgen receptor (AR), and estrogen receptors (ER) α and β in the mouse testis after 2 weeks of the lipectomy. The lipectomy of epididymal fat at 2 months of postnatal age resulted in significant increases of expression levels of cytochrome 5α-reductase I, cytochrome P450 aromatase, AR, and ER α and β.

Background: In recent years, depression has become a global public health concern, and one of the common concomitant symptoms are diminished sexual motivation and impaired sexual performance. The aim of this study was to investigate the potential effects of oligosaccharides (MOO) on depression and its concomitant symptom, sexual dysfunction.
Methods: Chronic unpredictable mild stress (CUMS)-induced depression model was constructed, and the effects of MOO on depression and sexual abilities were evaluated.
MT1/cAMP/PKA Pathway in Melatonin-Regulated Sperm Capacitation.

Melatonin is mainly synthesized and secreted by pineal gland, and plays multiple functions, including its regulating effects on reproductive processes. Sperm capacitation is necessary for fertilization, but the effect of melatonin on mouse sperm capacitation remains to be elucidated. We thus investigated the roles of melatonin on capacitation by culturing the sperms from mouse cauda epididymis in the medium with different doses of melatonin.

Objective: The study focused the contraceptive efficacy of hydro-ethanolic (60:40) extract (HEE) of Caesalpinia pulcherrima leaves in human and rat sperm samples by in vitro study.
Methods: Six young fertile adult males were selected for semen collection. Sperm samples were collected from six adult rat also by chopping the epididymis along with the collection of testicles, epididymis, and liver.

Objective: Many cancer survivors may experience irreversible infertility due to chemotherapy treatment for childhood cancer. In this study, spermatogenesis development was evaluated following the grafting of fresh and frozen-thawed testicular tissue from neonatal mice to the epididymal fat of adult mice.
Methods: After bilateral castration of recipient mice, fresh or frozen-thawed neonatal testis tissues were grafted into the epididymal fat of the mice.
